Conditions of Use
Recently in math class we have been learning all new and interesting elements of math. At the beginning of the module we started off reviewing last year's work. Then we moved into patterns and learned how to find the rule to a pattern and express it in algebra. Say if there were three numbers in a row and they were all random numbers I could figure them out and write the rule in algebraic form. We also learned how to make our own patterns.
After learning about all the tricks and gadgets that come with patterns we moved into algebra alone. Algebra was very interesting because instead of using all numbers and math symbols we used letters. Algebra is all expressed in letters and some numbers because it is a way find out a number if you don't know what it is. The algebra letter represents the number that you can't figure out.
Frequency tables and graphs were next on the list. We learned that a frequency table was the outcome, tally, and the frequency all together. You would use a frequency table when there were different say colors that kids liked and different amounts like one color. A frequency table is a way to organize all that information. After it is all put into the frequency table you can either make a bar graph or line graph. It really depends on the type of data. If it was a survey you would use a bar graph to show the information, and if it was showing the change in data over time then you would use a line graph to measure the change in data.
After we learned about tables and graphs we moved in to probability. We did a huge probability experiment when we chose some object to pick out of a bag and then we created a table and wrote a summary about our experiment. I learned a lot about experimental and theoretical probability and how to compare the two together. I worked with PJPH and we did our experiment on Razzles. We also used spinners to determine what was going to happen. We would find the theoretical probability of what would happen and then once we had spun the spinner we found the experimental probability.
Once we were almost done we still had to do the order of operations. This is just like PEMDAS which I learned about last year. It is when we took a number sentence and used PEMDAS order to find the correct answer. PEMDAS is a rhyme to remember that parenthesis come first and then exponents, multiplication and division are equal and so are addition and subtraction. You have to follow that order to get the true answer to the number sentence.
We are now done with module one so I wanted to inform you of what has been happening here in math class. I have been learning so much new and old nut all exciting information as you can tell. I will write soon! I have to continue learning all this information! Talk later!
